U4GM FH6 Guide to Motor and Battery Swap

There's a funny little upgrade challenge in Forza Horizon 6 that can trip people up, mostly because it doesn't feel like a normal engine swap. Instead of digging through petrol engines and drivetrains, you're working with an EV setup. You'll need the 2022 Honda E, a bit of menu hopping, and enough Forza Horizon 6 Credits to cover the car and the swap. It's not a huge job, but if you've never touched the electric conversion options before, it's easy to miss where the game hides it.

Getting the Right Car

The challenge is tied to the 2022 Honda E, so don't waste time trying it on every electric car in your garage. Head to the Autoshow and buy the Honda E if you haven't picked one up already. It's not one of those cars that drains your whole balance, which is probably why the game uses it for this objective. Once it's sitting in your garage, make sure you're actually inside the Honda E before opening the upgrade menus. Sounds obvious, but players do back out, swap cars, and wonder why the option isn't showing.

Where the Swap Option Is Hidden

From the garage, open Upgrades & Tuning, then go into Custom Upgrade. After that, look for the Body Kits and Conversions area. That's where you'll find the Motor and Battery Swap section. The upgrade you want is the 235BHP Motor option, and it costs 20,000 CR to install. Buy it, confirm the setup, and let the game apply the parts. You don't need to tune gearing, mess with tyre pressure, or build the car for racing right away. The challenge only cares that the motor and battery swap has been purchased and fitted properly.

What You Get From It

Once the upgrade is installed, the game should register the objective pretty quickly. You'll usually see a notification on the side of the screen showing progress for Discover Japan. In many cases, you'll get credit for owning the Honda E as well as completing the swap, so it can feel like a nice double tick for very little effort. If the notification doesn't appear instantly, back out of the garage or switch menus for a moment. The tracking can be a little slow, but it normally catches up without needing a restart.

Why It's Worth Doing Early

This challenge is useful because it teaches you how conversions work without forcing you into an expensive build. Motor and battery swaps can change the way an EV launches, pulls out of corners, and feels at higher speeds. The Honda E still won't suddenly become a hypercar, of course, but you'll get a clear sense of how one major conversion can alter a car's character. It's also a quick step toward the Car Upgrades title, which matters if you like collecting milestones rather than just chasing race wins.

Final Thoughts

The Motor and Battery Swap is one of the cleaner upgrade objectives in the game: buy the Honda E, open the conversion menu, install the 235BHP motor, and pay the 20,000 CR. That's it. It's cheap, quick, and a good excuse to learn a system you'll use again when experimenting with other Forza Horizon 6 Cars later on, especially if you enjoy making odd little builds that surprise people online.
